What should I pay attention to when assembling my own computer? What do you need to buy?

If it is used for games, you need to pay attention to the graphics card. In addition, you need to pay attention to the balance of CPU matching. The so-called balance means that the discrete graphics card is 0.2 to 2.0 times that of the 65438+CPU, and the office is biased towards the CPU (not very good, generally inteli3 series or below), so the discrete graphics card can be omitted. What needs to be purchased mainly includes the following 1 1 parts:

1, cpu (scattered cpu does not send radiator, boxed CPU comes with radiator).

2, cpu radiator (if you buy a "boxed CPU", you will get a CPU radiator, but the radiator given is small in diameter, high in speed and noisy).

3, the motherboard.

4, memory stick.

5. Hard disk (currently divided into mechanical hard disk and solid state hard disk).

6. power supply.

7. Chassis (you can understand the concepts of tower chassis and mini chassis. ).

8. discrete graphics card (if the performance requirements of graphics card are not high, you can buy APU or Intel cpu with front 1 components, and you don't need to buy a discrete graphics card).

9. Show.

10, keyboard, mouse.

1 1, headphones or speakers (you can choose one or both).

The most basic requirement of matching CPU and motherboard is that the interface should be corresponding, and the joke of A8-3870K matching 970Motherboard can no longer appear. Then there is the choice of the motherboard. The current high, medium and low-end motherboards are basically only functionally different.

At present, the interface layout of Intel products is high-end model LGA20 1 1, and mainstream model LGA 1 155. The last four digits represent the number of pins of the interface, one radish and one pit, which is easy to understand and can be installed accordingly. How to judge what interface it is? You can see the screenshot below. The CPU and motherboard in the product library will indicate the interface type.

AMD's interface type is a bit complicated. Although AM2/AM2+/AM3 are backward compatible, it means that the CPU is not compatible with the motherboard. For example, the AM3 processor can be used on the AM2 motherboard, but the AM3 motherboard does not support the AM2 CPU. This is because AM2 has 940 pins, while AM3 has only 938 pins, and their interface definitions are different. In addition, AM3 motherboard uses DDR3 memory, and AM2 CPU integrates DDR2 memory controller, which is also incompatible. To avoid confusion, we have listed the following table:

AM3 processor can be used in AM2/AM2+ motherboard because it integrates two sets of memory controllers, DDR2/DDR3. In fact, AM2/AM2+ products on the market have basically disappeared, so things are much easier. If you remove AM2 and AM2+, there is only one picture left:

Simply put, "AM3+ motherboard can be compatible with AM3 and AM3+ interface CPU, and AM3 motherboard can only use AM3 CPU". As for the brand-new APU and brand-new Athlon series, their unique FM 1 interface is used. Like Intel processors, only motherboards (A55 and A75) with corresponding interfaces can be used.
